It's done! After a long, long day of building yesterday, it is done! I added a simple mechanism which allows the arm's height to fluctuate while in midair, so as both arms collectively raise, one falls and the other rises by a slight-ish amount. I also added details and the black-red scheme looks pretty good IMO! Good pictures and a video will follow soon.

That is so cool! Definitely my favorite so far, I love how you combined manual and power functions and how everything works so smoothly!

Job: gearbox, shifter. Status: new shifter made, up to @Didumos69 to integrate it. Gearbox finished ages ago.

Thanks! I guess the motors are under the seats. Either way, I am only using 42043 stuff and the scale is too small for motors there, so yeah As for the seats, I might be able to make them artificially lean (i.e change the mounting so the seats lean).

Thank you! Though now I changed it because the gravity created some really jerky motion, so I changed it to this: The worm gear engages a multidirectional gearbox going to the outrigger block which then raises or lowers. I also have arms attaches, with the start of carts. For the carts, I'm taking a page out of @Akbalder 's book and decided to have them rotating freely. There's no space for a rotation mechanism.

Nope. I have no building time between Monday and the new due date so I have to finish it beforehand.

I would advise you to use 2 winches for the drill to help stabilize it, and to use a frame-heavy construction for the drill "module". Otherwise looking really good, keep it up!

Is the forklift height you show in the video the maximum height? If so, I find that to be a bit low.

This is actually so cool! I love how everything is automated. This is a serious piece of engineering.

Lego's official description stated it was more than 90% Lego, not 100%.

Very interesting! I can't wait to see a video of it working.

Looks decent but where did all the geartrains go?

This is pretty insane! What I like most is that sign. I hate riding these kinds of things, but the sign makes me want to go on this ride!

It honestly depends on that youtube algorithm. I've had a similar problem recently where one of my videos got 10k views, and then I uploaded another one which only got 1k views in 3 weeks. So you have to just go with the flow when it comes to youtube because you're never in control

Me too...

Thanks! I used a worm gear to engage and disengage a transmission to the red outrigger so it goes up with the gear train, and down using gravity.

Great build, but the proportions are way off and those A-pillars are horrid. The angle is so weird and throws off the look of the whole tractor.

I would recommend 42043, 42054, and 42055. All amazing sets and donors.

Hey everyone, As an abundance of 42055 c models that have popped up in this contest, I have decided to switch things up and use 42043 to build my ride instead. Is 1 week enough time? I don't know! We'll see. So my ride is based on SLEDGEHAMMER from Canada's Wonderland (really, it's a replication of its functions). So here's what I have so far. Th entire spinning-lifting mechanism with a base is basically done: And now, a video if you wish to see it work: https://drive.google.com/file/d/1jxaWpVv4XngpzkZbj0AHW_69PdvMFaet/view?usp=sharing (I'll put a better link soon) So that's all, thanks for reading and I hope you have some faith in a 1-week ride!

It's done! Thanks for the shoutout and how excellent this turned out of a giant build! The only thing I could say is that the boom looks really skinny for the scale and some more bodywork would benefit the superstructure, but no matter. This is an excellent build if I've ever seen one, and quite ambitious too!

Thank you! The second stage requires lots and lots of torque to deploy safely, so I don't see it moving with 0.5kg+. Yes, I fully agree. The outriggers were the hardest place to decorate, especially considering that I ran out of black. The light gray was not meant to be light gray by any means. I ran out of black beams constructing the chassis and the boom's first stage, so the LBG was a result of lack of parts. I do not own the set, but even if I did I would not sacrifice it. The large slewing ring would have really saved me as the superstructure could have really benefitted from 1 or 2 studs more of elevation. If I could have reused it I would have. It does work better on 42054 because the lever that controls the rear axle's angle sat directly on the rear axle. in the case of this crane, that cannot happen as a result of the suspension. Therefore one extra member needs to be added between the steering mech controls and the rear axle, which increased the play a lot. It actually worked fine when the superstructure was not attached to the chassis, but the added weight really caused the majority of the play. In 42054 there was a lot less weight on the axles. I don't think TLG cared about whether there's an extra step or not. What I think they realized is that they couldn't make 2 stage outriggers extend far enough to be significant. The 42043 had those outriggers and they didn't look like much albeit being a big feature of the model. As for my model having the manual step, without the red sliding 8t gears it became impossible for me to drive LA's on the tip of the outriggers. Before unifying the chassis, I spent a few days trying, but it didn't work out. I think the main culprit of this is that the housing takes up way more space they should; I found it very hard to engineer around them. Maybe TLG realized it too but didn't want to go with the 42009 setups, so they stuck with the outriggers they have.

I disagree. There seems to be some space around the valves on both sides the way @mpj has them set up, so I'm not sure why they wouldn't fit. If anything, they might make things easier because their total height is 1 stud when laid out flat.

This mod is not only really cool but also makes lots of sense. It would have been much more logical to make this set the pneumatic one as opposed to 42080.

In terms of the messing up the rotation, maybe adding the third module will improve the weight distribution and therefore allow the structure to rotate. Additionally, adding some more gear reduction before the turntable will help (and maybe removing the white clutch gears and replacing them with regular 24z gears). Is this being built from the pieces of the 42055?

I'll be posting mine tomorrow as soon as I have created a working "sequence" mechanism.
